What is the difference between the velocity operated and pressure operated microphones?
Know your microphones - what is the difference between pressure, pressure gradient, and velocity microphones?David Mellor | November 30, -0001Microphones work on the principle of pressure, pressure gradient, or velocity. If you don't know the difference, then you can't yet call yourself a sound engineer.This is something from the text books. Actually you don't have to know this to be a sound engineer - the proof of that is the 90% of sound engineers that don't know it! Yet a little theory never hurt anyone. And if you know how things work in theory, then you can apply them better in practice.There are two basic types of microphone - omnidirectional and figure-of-eight, which can be made in either dynamic or capacitor forms. Cardioid and hypercardioid microphones are hybrids, combining features of both the omni and figure-of-eight.The omnidirectional microphone works on the pressureprinciple. The diaphragm, which picks up sound vibrations in the air, is completely open at one side, but completely closed at the other.The sound vibration is either pushing the diaphragm against the fixed pressure of the air on the other side, or it is reducing the pressure on the front of the diaphragm allowing the pressure behind to push it out.One of the features of pressure in a gas is that it pushes equally in all directions. "Equally in all directions"? That makes the mic omnidirectional then.[For the sake of completeness, it should be mentioned that there is a tiny hole in the capsule to the rear of the diaphragm. This is so the microphone can compensate for long-term variations in air pressure. The hole is too small to affect its sound characteristics.]The figure-of-eight microphone on the other hand has both sides of the diaphragm fully open to the air. So it doesn't compare the incoming sound pressure with a fixed pressure on the other side of the diaphragm like the omnidirectional microphone. Instead it compares the pressure of the sound wave on one side with the pressure of that same sound wave after it has traveled through to the other side.Yes, it is a tiny difference in pressure, but strong enough to move the diaphragm.The difference in pressure between the front and the back of the diaphragm depends on the angle of incidence of the sound wave. In the extreme, if the sound arrives from the side of the diaphragm, then the pressure will be the same at the front and the rear, therefore the diaphragm will not move and there will be no output.Lastly, the velocity microphone... it doesn't exist! However you will see the term used frequently, particularly in relation to ribbon microphones.A velocity microphone, if it existed, would respond to the actual velocity of the air molecules striking the diaphragm.For this to happen though, the diaphragm would have to be so light that it could respond almost instantaneously, and so thin that there was no pressure difference between the two sides of the diaphragm. In practice, the diaphragm is too heavy to acquire the velocity of the air molecules and it has significant thickness.But a microphone that doesn't make it as a velocity mic, because its diaphragm is too heavy and thick, is still sensitive to pressure gradient. So in practice, these microphones are pressure gradient mics.So now you know it - the difference between pressure, pressure gradient and velocity microphones.
Causes of low oil pressure?
Low oil pressure can be caused by multiple faults. A blown gasket, a cracked head, a leak in the line, or even a low level can cause low oil pressure.
Does pressure affect changes of state?
Yes, pressure can affect changes of states in matter. Increasing pressure can help compress gases into liquids or solids, while decreasing pressure can cause liquids to evaporate or solids to sublimate directly into gas.
What 2 factors affect the behavior of liquids?
Two factors that affect the behavior of liquids are temperature and pressure. Temperature influences the movement of molecules within the liquid, affecting viscosity and evaporation rate. Pressure can influence the boiling point and compressibility of the liquid.
Does the type of liquid affect what the rate of evaporation?
Yes, the type of liquid can affect the rate of evaporation. Liquids with lower viscosity and higher vapor pressure tend to evaporate more quickly than liquids with higher viscosity and lower vapor pressure. Additionally, the presence of solutes in the liquid can also affect the rate of evaporation.
Does change in pressure affect the solubility of solids?
The solubility of solids and liquids show virtually no changes with pressure. However, solubility increases with pressure in the solubility of gases in liquids.
How does different liquids affect roses?

How does pressure affect the solubility of gases in liquids?
Increasing pressure typically increases the solubility of gases in liquids because the gas molecules are forced into the liquid by the higher pressure. This is described by Henry's Law, which states that the solubility of a gas is directly proportional to the partial pressure of that gas above the liquid. Conversely, decreasing pressure tends to decrease the solubility of gases in liquids as the gas molecules can escape from the liquid more easily.
Is the boyle's law applicable to liquids?
Boyle's law applies to ideal gases, not liquids. In liquids, pressure and volume are not directly proportional as they are in gases. Liquids are generally considered to be incompressible, so changes in pressure do not significantly affect their volume.
What effects pressure?
Pressure can affect the physical properties of gases, liquids, and solids. For gases, pressure influences volume and temperature through the ideal gas law. In liquids, pressure can impact density and boiling point. In solids, pressure can cause compression or expansion, altering the arrangement of atoms and thus changing the material's properties.
Are there liquids on Mars?
No, it doesn't have enough atmospheric pressure to support liquids.
What are devices whose operations depends on pressure of liquids?
Some devices that operate based on the pressure of liquids include hydraulic systems for machinery, pressure sensors for measuring fluid levels, and pressure relief valves for controlling the flow of liquids in pipelines.
How do pressure differences affect the direction in which fluids flow?
Were liquid is more, you have more pressure. Liquids, and gasses flow from higher pressure areas to lower pressure areas, like people in a bus. If it's crowded is a place, they go were it's less crowded.
Why do some liquids travel faster than others?
The speed at which a liquid travels is influenced by its viscosity - the resistance to flow. Liquids with lower viscosity flow more easily and thus typically travel faster than liquids with higher viscosity. Other factors such as temperature and pressure can also affect the speed at which liquids travel.
